Relations and Functions board questions with solutions are discussed here.

Practice Relations and Functions in Maths

MCQ QUESTIONS RELATIONS AND FUNCTIONS

WHAT ARE RELATIONS AND EQUIVALENCE RELATIONS

This post gives you the basic definition of a relation followed by the meaning of the Identity relation, Universal relation and the Empty relation. You will learn about reflexive, symmetric and transitive relations and an Equivalence relation. 2 problems are also illustrated. The first problem helps you to identify whether the given relation is reflexive and symmetric. The second problem gives you a relation and you are asked to identify it.

INTRODUCTION TO FUNCTIONS

What are sets, relations and functions? This presentation starts with the Cartesian product of 2 sets and how a relation is defined from it. It also goes on to show how this leads to a function . Some of the problems include : If (a,-2), (4,b*b) belongs to R, where R= {(x,y): x, y are integers, y = 2x-4, }, find a and b Find the domain and range of R={(x, y): x, y belong to N, x+ y=10} A={1,2,3,4}, B={1,5,9,11,15,16}, f={(1,5), (2,9),(3,1),(4,5),(2,11)}. Is f a function from A to B Draw the signum function We cover the different types of functions and problems based on them. Types of functions explained are one-one, onto, many to one and into functions. Online classes are provided. You can choose between specific topics or the entire course.

MCQ TYPE QUESTIONS- RELATIONS AND FUNCTIONS

This video helps you to answer objective questions on Relations and Functions. Topics covered are equivalence relations, functions, one one and onto functions. In my three decades of experience as a math educator, I have found students losing marks in 1 mark questions because that is where you need to know the topic inside out. This video teaches you intricate details about the number of functions from a finite set to another finite set, the number of one-one , onto, and bijective functions.

INVERSE TRIGONOMETRIC FUNCTIONS FORMULAS

I am just trying to make problem solving in Inverse Trigonometric Functions easy for you by presenting you with a set of formulas. While mathematics is not about learning formulas, this is a last minute revision for you. Inverse Trigonometric functions is not an easy topic as such. The lesson starts with the domain and range of the six inverse trigonometric functions. We then proceed to finding the principal values, a very likely question in your exams. These can be solved using a few simple techniques as illustrated. We then proceed to finding the value of the reciprocal of an angle and then move on to the basic sum and difference formulas. As a math educator, teaching math for over two decades, I believe these formulas will greatly enhance you last minute exam revision.
